Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80712, here are decompositions:
- 11 + 80701 = 80712
- 29 + 80683 = 80712
- 31 + 80681 = 80712
- 41 + 80671 = 80712
- 43 + 80669 = 80712
- 61 + 80651 = 80712
- 83 + 80629 = 80712
- 101 + 80611 = 80712
Showing the first eight; more decompositions exist.
